    Thread moved to Homework Help forums. Welcome to the PF, nls123. Homework and cousework (and geocaching!) problems need to be posted in the appropriate Homework Help forum, not in the general forums.

    And another rule that we have here is that you must show us your work so far, in order for us to help you. We do not give out answers, but we are happy to help coach you along, as long as you show some genuine effort of your own.

    Show us your work so far on these two questions. What are the relevant equations to use, and how have you applied them so far?
